Removable Connector Support for Junction Box Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electric junction box assemblies do not allow access to the bottom cover floor without disconnecting the connector assembly, limiting packaging options and maintenance.
Innovation Solution
A junction box assembly with a removable connector support that is rotatably coupled to the bottom cover, featuring a latch mechanism and open retention feature to securely hold the connector assembly in place, allowing the floor to be accessed without disconnection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the connector assembly is integrally formed to the bottom floor, then the structural strength is improved, but the accessibility to the bottom cover is worsened
Solution Approach 1:
The bottom cover is segmented into two functional parts: a fixed bottom floor and a removable connector support. The connector support is detachably coupled to the bottom floor, allowing it to be removed independently to access the bottom cover interior while the bottom floor remains intact. This segmentation resolves the contradiction by enabling access without compromising structural integrity.
Solution Approach 2:
The connector assembly is extracted from the integral structure and placed on a separately removable connector support. This allows the connector support to be taken out to access the bottom cover, while the bottom floor retains its structural strength. The extraction principle enables independent access to the bottom cover interior.
2Reliability
If the connector assembly is fixed to the bottom floor, then the reliability of electrical connection is improved, but the adaptability for maintenance is worsened
Solution Approach 1:
The system is segmented into a fixed bottom floor and a removable connector support. The connector support can be removed for maintenance while the bottom floor remains fixed, providing maintenance flexibility without compromising electrical connection reliability when assembled.
Solution Approach 2:
The connector support transitions from a fixed state (when assembled) to a removable state (when detached). This dynamic design allows the connector support to be securely attached during operation for reliable electrical connections, yet easily removed when maintenance is needed, resolving the contradiction between reliability and adaptability.
3Object-affected harmful factors
If the bottom cover is sealed to protect against water ingress, then the protection level is improved, but the accessibility for component removal is worsened
Solution Approach 1:
The bottom cover is segmented into a sealed bottom floor and a removable connector support. The bottom floor maintains the waterproof seal, while the connector support can be removed independently to access components. This segmentation allows water protection to be maintained while enabling component accessibility.
Solution Approach 2:
The connector support is extracted as a separate removable component from the sealed bottom cover structure. This allows the bottom cover to remain sealed for water protection while the connector support can be taken out for component access, resolving the contradiction between protection and accessibility.

AI summary
A junction box assembly configured to provide access to a floor of the bottom cover without having to disconnect the connector assembly is provided. The junction box assembly includes a removable connector support. The connector support is configured to hold a connector assembly. The connector support is removably attached to a bottom cover so as to provide access to a floor of the bottom cover. In one embodiment, the connector support is rotatably attached to a bottom cover of the junction box assembly so as to move between an open position and a closed position, wherein in the closed position a floor of the bottom cover is covered and in the open position the floor is exposed.
